Introduction:People spend about 90% of their time indoors. Most health problems associated with indoor air quality are caused by fungi. It is estimated fungi account for 70% of total indoor air microbial pollution.Purpose: To analyze fungal pathogens isolated from indoor air of Branicki Palace in Białystok, PolandMaterials and methods:The research mycological material consisted of air collected from various rooms in Branicki Palace. Humidity and temperature of the tested rooms were also measured. The monitoring of airborne fungi pollution was done using a SAS SUPER 100 (pbi international) with international measure standards (EN 50081-1, EN 500 50082-1). Biological monitoring of wall surface contamination was performed using the Count-Tact applicator with Count-Tact plates.Results:A total of 1140 CFU per m3 of air were cultured in autumn and 580 CFU in winter. From the walls, a total of 124 CFU were cultured in autumn and 397 CFU in winter. CFU values in the investigated rooms ranged from 10 to 220 (mean 47 CFU) in autumn, and from 10 to 90 (mean 29 CFU) in winter. The most commonly isolated pathogens were: Candida albicans, Aspergillus sp.,non-Candida albicans, andPenicillium sp.. The number of colonies isolated from the walls of all rooms in winter was greater than in autumn. The most commonly isolated pathogens were: Aspergillus sp. andC. albicans in autumn; C. albicans and non-C. albicans in winter.Conclusions:In winter, the number of colonies isolated from walls in all rooms was significantly greater compared with autumn. Candida albicans, Aspergillus sp. and Penicillium sp. were the most commonly isolated fungal air pathogens, regardless of season. C. albicans and Aspergillus sp. were most commonly isolated from walls in autumn, while C. albicans and non-C.albicans in winter.

This study was conducted with a view to evaluating the physicochemical and mycological properties of different oil contaminated soils collected from three different automobile garages in Sokoto Metropolis, and uncontaminated soil from the temporary site, Usmanu Danfodiyo University, Sokoto (UDUS) was used as the control. The pH was determined using pH meter model Hanna (H1991301), quantity of mineral elements was evaluated in accordance with Murphy and Fungi were isolated from the three oil contaminated samples (A, B. and C) and the uncontaminated (sample D) as control, this was done by standard procedure using the method of P. Ren, T. Jankun & B. Leaderer. The physical, chemical, and mineral elements from the oil-contaminated soils of the three automobile garages and control. The results of particle soil analysis revealed the high content of sandy soil (96.2 to 87.3) and silt is the lowest with (2.5–0.6). Magnesium had the highest concentration of studied minerals, ranging from 193 to 649.2 mg/kg. while PH result revealed that the soil samples were pH value ranged from (16.85–16.20) in oil Contaminated samples, while the control had 15.90, and electrical conductivity ranged from 12.8–13.8 % and 28 % in control, four fungal isolates Aspergillus sp., Penicillum sp., Mucor sp. and Sporobolomyces sp. were identified based on colonial, sexual and morphological characteristics. These fungal strains can be used in bioremediation process and oil pollution reduction in aquatic ecosystems.
